Definitions

  • aqueous dispersions which esssentially contain waxes, lanolin, polyurethane resins as the principal film formers, polymeric polycarboxylic acids as pH-regulators and nonionic emulsifiers in a selected composition and which are free from low-boiling organic solvents are eminently suitable for the care of sensitive leathers, particularly natural and mat leathers.
  • the present invention relates to a liquid shoe- and leather-care preparation in the form of an aqueous dispersion having a pH-value of from 7 to 8, wherein the nonaqueous constituents are as follows, in which the parts by weight are based on the total weight of the nonaqueous constituents:
  • the compositions of the invention are distinguished by the fact that light, pastel-colored, uncovered or substantially uncovered leathers treated with it no longer darken or turn patchy, while natural leather, leather finished with a silk-like sheen or mat leather are not spoiled by an excessive build up of gloss. These results are achieved without having to relinquish any advantages, such as the formation of non-marring, elastic and flexible films, the care of the leather by lanolin, and elimination of the need for polishing.
  • the compositions of the invention are not limited in their application to the care of low-shine leathers of the type mentioned above because the films which the present compositions produce do not in any way affect the shine of glossy leathers. Accordingly, the new compositions can be universally used for all types of leather.
  • the waxes (constituent a) above) present in the instant compositions are natural waxes, such as candelilla wax or carnauba wax, or chemically modified montan waxes of the montanic ester wax type. Montanic acid ester waxes having acid numbers of from about 25 to about 35, saponification numbers of from about 115 to about 155 and a dropping point of from about 75° to about 90° C. are particularly suitable.
  • lanolin is separately set forth as a constituent (b) above), because not only does it contribute towards film formation, it also largely determines the caring properties of the composition.
  • Purified lanolin which is preferably used for the compositions of the invention, has the following average characteristics:
  • polyurethane resins consisting of the many known polyurethane resins (constituent c) above), dispersible, film-forming aliphatic types are used in the present compositions.
  • Polyurethane resins such as these which can also be slightly crosslinked, are produced in one or more successive addition reactions from aliphatic diisocyanates and aliphatic diols and, optionally, relatively small quantities of aliphatic diamines which serve as chain extenders.
  • Suitable diisocyanates are, for example, hexamethylene diisocyanate and 4,4'-diisocyanatodicyclohexylmethane.
  • Particularly suitable diols are hydroxyl-terminated aliphatic polyesters of the type obtained, for example, from adipic acid and short-chain aliphatic diols containing from 2 to 6 carbon atoms or hydroxyl-terminated polyesters of the type obtained, for example, by the polymerization of ethylene oxide, propylene oxide or tetrahydrofuran.
  • low molecular weight diols such as ethylene glycol and 1,6-hexane diol
  • their function like that of the aliphatic diamines, for example ethylene diamine and hexamethylene diamine, is the chain extension and modification of already formed polyurethanes still containing isocyanate groups.
  • the molar ratio of diisocyanate to the sum of its addition partners can be between about 1.0 to about 0.8 for the polyurethane resins usable herein.
  • the above described polyurethane resins give elastic films which rapidly reach the necessary non-marring point and which withstand even severe stressing in wear without any need for further resin-like or polymeric film formers, such as polyacrylates or polyethylenes.
  • Particularly favorable properties are shown by those compositions in which the polyurethane resins have been produced from aliphatic diisocyanates containing from 8 to 38 carbon atoms and hydroxyl-terminated aliphatic polyesters having an average molecular weight of from about 500 to about 5000 or aliphatic, hydroxyl-terminated polyethers having an average molecular weight of from about 200 to about 6000.
  • Suitable polyurethane resins are commercially available, including for example the already dispersed products manufactured by Polyvinyl Chemie which are marketed under the name of NeoRez®:
  • water-soluble polymeric poly-carboxylic acids are added to regulate the pH-value which should be between about 7 and about 8 in the compositions of the invention.
  • These polymeric polycarboxylic, acids stabilize the pH-value against random fluctuations, so that any shift toward ranges which would cause sensitive leathers to darken is avoided without affecting the properties of the film on the leather.
  • Suitable pH-regulators are the water-soluble homopolymers of acrylic acid, methacrylic acid and maleic acid and also the water-soluble copolymers of those monomers with one another and with other polymerizable molecules, such as alkylvinyl ethers and olefins.
  • Polyacrylic acid having an average molecular weight of from about 1000 to about 100,000 is preferably used herein.
  • the emulsifiers used are nonionic compounds of the type obtainable, for example, by reacting ethylene oxide with long-chain alcohols, alkyl phenols or fatty acid amides. It is preferred to use the reaction products of from 6 to 30 moles of ethylene oxide and primary alcohols containing from 12 to 18 carbon atoms or alkyl phenols containing from 6 to 14 carbon atoms in the alkyl group.
  • water-soluble hydroxyalkylamines containing from 2 to 12 carbon atoms preferably mono-, di- or triethanolamine, enhances formation of the dispersions.
  • compositions of the invention are absence of readily volatile organic solvents, such as petroleum fractions, chlorinated hydrocarbons or terpenes, and of alcoholic solvents which, in conventional preparations, have frequently upset the water balance in the leather and have resulted in embrittlement of the leather.
  • organic solvents which are normally used as flow promoters for improving film formation, such as tris-(ethylhexyl)-phosphate, isophorone and, preferably, N-methyl pyrrolidone, can be used herein (optional constituent h) above) without any adverse effect upon the caring properties.
  • compositions of the invention can contain other ingredients (optional constituent g) above) of the type commonly used in shoe-care preparations, providing they are compatible with the other constituents.
  • Ingredients such as these include, for example, perfume oils, preservatives, foam inhibitors and dyes and also emulsifying aids which may be present, for example, as residual impurities in prefabricated starting materials.
  • the dispersions can readily be prepared by stirring the individual constituents into water in any suitable sequence.
  • two or even more constituents for example lanolin, wax and the emulsifier, are usually premixed, optionally with heating, and then mixed together with the other constituents. It has proved to be of particular advantage initially to convert one or more constituents into a dispersion of, optionally, relatively high concentration and then to add the remaining constituents to that dispersion. This procedure is best adopted in instances where commercially available polyurethane dispersions are used.
  • aqueous dispersion having the following composition was prepared (% by weight is based on the total weight of aqueous dispersion):
  • the dispersion was prepared in several stages. First, an approximately 20% wax emulsion was prepared by melting the montanic acid ester wax, lanolin, emulsifiers and diethanolamine and stirring the resulting melt into water. A calculated quantity of the emulsion thus formed was then diluted with more water, followed by addition of the prediluted polyacrylic acid, the preservative, the perfume, and the foam inhibitor. Finally, the NeoRez 962® (Polyvinyl Chemie) which already contained the N-methylpyrrolidone was added to the polyurethane dispersion with thorough stirring.
  • NeoRez 962® Polyvinyl Chemie
  • the milky, free-flowing dispersion formed of which the nonaqueous component amounted to 5.7%, had a pH-value of 7.8. It was eminently suitable for treating mat and natural leathers to which it could be applied by means of a sponge or cloth, but advantageously from a suitable dispenser with a foam applicator.
